Visual Studio TestStack.White NuGet

Question

我試圖通過「管理NuGet包」來安裝TestStack.White，每次出現此錯誤。

Install failed. Rolling back... 
Failed to initialize the PowerShell host. If your PowerShell execution policy setting is set to AllSigned, open the Package Manager Console to initialize the host first. 

任何想法如何克服這個錯誤？
